Missy: I'm glad Mom didn't come.
George Sr.: Why's that?
Missy: I can spit when I'm on the mound.
George Sr.: You can hock up anything you want today.
Missy: [snorts]
George Sr.: Not here.
Missy: Aw.

Lawrence: I like your conductor's uniform.
Sheldon: You know what they say. Dress for the job you want. Do I get an "ask me" button, too?
Lawrence: Well, thank you for asking, and yes, you do. I'll be right back. [exits]
Sheldon: Do you see that bell? That's from Texas and New Orleans locomotive number 701. I'd tell you more, but you haven't contributed the suggested donation.
[Sheldon stares at Meemaw until she puts some money in the donation box]
Sheldon: Number 701 was built in 1930 by the Baldwin Locomotive Works. It was a superheated 44 class GS-1 with ...
Meemaw: I want my money back.
Lawrence: Here you go.
Sheldon: Thank you. [to Meemaw] I know you're supposed to pick me up at 4:00, but I may live here now.
Meemaw: Send me a Christmas card.

Sheldon: Thanks for bringing me.
Meemaw: Hey, it got me out of driving all the way to Missy's game; I should be thanking you.
Sheldon: [knocks] My little knuckles might not be cutting it. Would you give it a go?
Meemaw: Sure. [knocks] How's that?
Sheldon: Four knocks. Bold.
Lawrence: [opens door] Hello, hello.
Sheldon: Volunteer docent Sheldon Cooper reporting for duty.
Lawrence: Welcome aboard.
Sheldon: Train nomenclature right out of the gate. Promising.

Mary: Sheldon, you sure about this?
Sheldon: Yes, leave the crusts on. I'm a docent now.

George Sr.: What do you got going on today?
Mary: Ooh, laundry, grocery shopping, vacuuming. I might go nuts and dust the picture frames.
George Sr.: Well, nice. Everybody's doing something they love.

Mary: What time is the game?
Missy: 12:30.
Sheldon: Why are we talking about baseball and not my impending docent-hood?
Missy: Who wants to tell him it's stupid?
George Sr.: Leave it alone.
Missy: And why do they make you wear that goofy costume?
Sheldon: Ha. They don't. This is all me.

George Sr.: We should hit the road soon. It's a long drive.
Missy: Okay.
Mary: I got your lunches here.
Missy: Extra Fruit Roll-Ups?
Mary: You each got two.
Missy: Thank you.
George Sr.: Thank you.

Sheldon: [on the phone] Hello. I understand you're looking for a docent. I'm 11 years old, but you should know I have a high school diploma and I know more about trains than anybody. You still sound on the fence.
Adult Sheldon: It was time to break out my unique ability.
Sheldon: Let me tell you about every model train I own and what each of them means to me. The first locomotive I ever received...
Adult Sheldon: Wouldn't you know it, 47 short minutes later, I got the job.

Sheldon: The train museum's looking for a docent.
Mary: What's a docent?
Sheldon: It's a person in a museum who gives information on the exhibits.
Mary: Do you think they'd let someone your age do that?
Sheldon: Why not? I have a high school diploma.
Mary: True.
Sheldon: I know more about trains than anybody.
Mary: True.
Sheldon: And I have the unique ability to wear people down until I get my way.
Mary: So true.

Adult Sheldon: Presenting... "Sheldon Cooper's Top Five Sources of News From My Childhood". Number five: Star Trek Fan Club Magazine.
Sheldon: Mom, DeForest Kelley's favorite episode is "The Empath."
Mary: Good to know.
Adult Sheldon: Number four: the Weather Cube from RadioShack.
Man: [from device] The humidity is 90% with a dew point of 79.5 degrees.
Sheldon: Mom! The dew point is 79.5 degrees.
Mary: [o.s.] Okay.
Adult Sheldon: Number three: The MacNeil/Lehrer NewsHour. Such a great theme song.
Sheldon: [hums] Buh-buh-bum.
Adult Sheldon: Number two: Meemaw after a few beers.
Meemaw: It took a while, but we finally picked a new name for my bowling team: The Ball Busters.
Sheldon: Hey, Mom. Guess what Meemaw named her bowling team? The Ball...
Adult Sheldon: And the number one source of news from my childhood: the bulletin board at the train store. News about trains in a store full of trains. Yummy.
Sheldon: How did this not make The MacNeil/Lehrer NewsHour?

Adult Sheldon: Later that day, we had a graduation party for me and my sister. I don't normally care for parties, but this one wasn't so bad.
Mary: Who's ready for cake?
Missy: Me!
Dale: Hey, should we say grace?
Mary: Heck, yeah! Let's hold hands.
Meemaw: Oh, cool. Let's say grace.
Adult Sheldon: Dale invited Jesus to the party, and while he wasn't on my guest list, it was okay because it made my mom happy.
Mary: And bless our friends and family...
Adult Sheldon: In fact, it was the best graduation party I had ever been to, until the one we had for my son, Leonard Cooper.
All: Amen.
Missy: Cake!
Adult Sheldon: I wanted his name to be Leonard "Nimoy" Cooper, but Amy wouldn't let me.
Amy: Be happy I let you name him Leonard!
Adult Sheldon: Okay, okay!
Amy: Love you.
Adult Sheldon: Love you, too.

Adult Sheldon: The following day, I attended my sister's elementary school graduation. She didn't deliver a speech to me, but she did make eye contact while she sang "This Land Is Your Land."
Kids: [sing] From the Redwood Forest To the Gulf Stream waters This land was made for you and me...

Principal Petersen: Our next young speaker needs no introduction, but that didn't stop him from writing one and making me read it. [laughter] "Fun fact." [audience groans, murmurs] I hear you. "The word 'valedictorian' is from the Latin 'valedicere,' meaning 'to say farewell.' It is primarily used in the United States, Canada, the Philippines and Armenia." Maybe that fact's more fun in Armenia. Please welcome your valedictorian, Sheldon Cooper.
Mary: Yay, Shelly!
Sheldon: Hello. I'm not very comfortable speaking in front of crowds. But there's a technique to reduce stage fright by focusing on one person in the audience and delivering your speech just to them. That's what I'll be doing today. If it weren't for this person, I wouldn't be here right now. They've taught me a lot, and it's by their example that I found the courage to move forward into this new and exciting chapter of my life. Missy... ...this is for you. Change can be scary, but I know we're going to be fine... ...because like you said, "It's okay to be scared. We just have to do it anyway." So if any of my fellow graduates are nervous about the future, know that you're not alone. I suggest you all try to be as brave as my twin sister. That's my plan. Missy, I wish I could give you advice about middle school, but I was so smart, I skipped it. If you make it to high school, we'll talk. Thank you. [applause]

Sheldon: [knocks three times] Mom? [knocks three times] Dad?
Mary: [o.s.] Yeah, baby? [Sheldon opens his parents' bedroom door]
Sheldon: I'm ready to graduate. Good night. [exits]
George Sr.: That's because I supported him.

Missy: I get it.
Sheldon: What do you get?
Missy: Why you don't want to go to college.
Sheldon: I doubt that you do.
Missy: You're scared everything's gonna be different and it'll be hard. And you're gonna miss the way that it was.
Sheldon: How do you know that?
Missy: 'Cause that's how I feel.
Sheldon: You're scared?
Missy: Yeah.
Sheldon: So what do we do?
Missy: I guess be scared and do it anyway.
Sheldon: Hmm. It's comforting to know that you feel the same way that I do.
Missy: That's why I said it, dumbass.

Mary: Here you go, baby.
Sheldon: I don't know if I can go to college next year.
George Sr.: Are you kidding me?!
Mary: George.
George Sr.: Buddy, I know you're upset. But are you kidding me?
Mary: Don't listen to him. There is no pressure. If you want to spend another year in high school, that is your decision.
Sheldon: I don't know. May I be excused?
Mary: Uh, of course. [looks at George Sr. as Sheldon walks off]
George Sr.: We support you, buddy!

Kimberly: Sheldon, tell us what you're gonna miss the most about high school.
Sheldon: Nothing.
Kimberly: Really? Not your teachers, your friends?
Sheldon: I only have one friend. And I don't think he's gonna miss me because he already found other people to have lunch with.
Mary: Oh, I'm sure he'll miss you.
Sheldon: And I said I'm okay with watching Professor Proton at night, but that'll never work. I get overtired... everybody knows that!
George Sr.: Maybe we could turn the camera off.
Sheldon: And the other day, I couldn't find my safety goggles and I freaked out in school, and my dad asked is this how I plan on acting when I get to college, and I said no, but it probably is because even though I'm smart, I'm just a little boy!
Kimberly: I think we have enough.
George Sr.: Cut.

Sheldon: I was a little worried about missing Professor Proton, but I'm going to tape it and watch it at night. Once I'm in college, can we push my bedtime to 8:30?
Mary: Let's talk bedtime when we're not on the news, honey.
Sheldon: I'm sure it'll work out since I have all summer to recalibrate my bathroom schedule.
Mary: Let's not talk about that, either.

Kimberly: We're here with the Cooper family. Mary, George and eleven-year-old Sheldon, who's going to be Medford High School's valedictorian. Mom and Dad, you must be so proud.
George Sr.: Oh, very proud.
Mary: But we're proud of all of our children.
Sheldon: She has to say that.

George Jr.: Hey, can I ask my girlfriend to the prom on TV? It would blow her mind.
